SKU CH-PZYQ-J33ET

Replacement power button board with ribbon cable for Dell Latitude E6400 palmrest G895P

Exact fit for Latitude E6400

This replacement power-button board carries Dell part number H572N and is designed solely for Latitude E6400 units that use palmrest assembly G895P. It restores the on/off switch and WiFi catcher function on the original touchpad palmrest. Buyers with a different palmrest part number cannot use this board.

Passive component, no thermal load

The board draws negligible power and generates no measurable heat or noise during normal operation. It connects through the existing ribbon cable to the motherboard and operates only when the power button is pressed. No additional cooling or power budget is required.

Ribbon cable included, screws not supplied

The listing provides the flex cable needed for installation, but mounting screws are absent and must be sourced separately. No driver, firmware or software bundle accompanies the part. Installation is a direct swap once the correct palmrest is confirmed.

Questions about this item

How do I install the H572N power button board on my Latitude E6400?

Remove the palmrest assembly, disconnect the old ribbon cable, connect the new board's ribbon cable to the motherboard header, then secure the board onto the G895P palmrest.

What maintenance will the H572N power button board require?

No scheduled maintenance is needed; if the button becomes unresponsive or the ribbon cable frays, replace the entire H572N board.

What is the first limit I will hit if I use the power button constantly?

The mechanical switch life and ribbon cable flex endurance determine longevity; heavy use will wear the tactile button or fatigue the cable first.
